How to open native calendar app from our app in iOS 6.1?

Question

I have tried to open the native iOS calendar app from within my app using the following code:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"calshow://"]];

The above code works perfectly in iOS 7 and I am able to view my calendar app,
but, the code does not work in an iOS 6.1 simulator.

I guess it is not supported in iOS 6.1. Please do provide any suggestions or workarounds for this. Thanks !

PS: Yes, I'm aware of the features of the EventKit(UI) frameworks. But I'd like to specifically open the iCal app.
and
Yes I went through the stackoverflow answer.

Simulator doesn't have a Calendar app. You can only do it on actual device.
